I believe 1 sample offset is correct for digi interfaces. Theoretically you cannot be reading and writing the same sample at once, hence the 1 sample delay.

The problem is difficult to explain and many people are totally unaware that it happens.

FYI. Once you've recorded an overdub, you can change the "user offset" delay at the bottom of mix view strips to -X where X is you offset and all will line up on playback. In my case, its -72.

Don't forget to change it back to 0 before recording on that track again - or you offset will get worse. Negative values push the wav file back when recording. Kinda like what we're asking for - but in the opposite direction!

Hi,
I am also a new PT user and have grown accustomed to the ability to test my system once and set it for compensation.

I run a MOTU 896HD with extra inputs coming in via ADAT.

In SONAR, the app allows me to augment what is automatically determined to be the correct compensation with a manual input to reflect that actual real life need.

My experience is that many people do not take the sync seriously... but I wish to have perfect sync and so this interests me greatly. When I started in DAW I thought this issue was a huge downside and was relieved greatly when SONAR provided a semi automated solution.

BTW, I created a Gearslutz thread a few weeks back after doing some testing. It turns out that at default settings PT9 compensates exactly the same as Sonar and the audio ends up exactly 1 sample behind. You can see my findings along with screenshots here:
